I used CCleaner to clean cookies & index.dat files from IE7. Rebooted couple of times, opened /closed IE a few times (loading websites each time). All other index.dat files stored under other accts were all cleaned at the same time - no issues w/ them. Two index.dat files and subfolders in my main acct (only that one) don't show up in explorer like they should. Other accounts still display properly, but don't all have an index.dat in all the 'normal' folders - no internet activity under them. You say, "That's great! Tell me how to get rid of the *%!#@$* index.dat files for good!" Well...they're still there, they just don't show up in Explorer, for that one acct. Who cares? Cause I know they're there, but can't see them. We have to use IE to log into certain sites, like work. I want to be able to delete the files (sometimes), and verify that. Apps like Kaspersky AV CAN see the index.dat files in both problem folders - the History.IE5 and Content.IE5 subfolders, when I scan the folders. Free Commander file mgr can see them - sort of. It can NOT see the History.IE5\index.dat, but CAN see content.IE5\index.dat - but only shows it in the right pane, not in the folder tree. I booted in safe mode under another administrator acct. At first I couldn't see the MIA folders / files in the problem acct. I deleted the problem folders & files, then restored them, & then I could see everything in Explorer. Logged back in under the main (problem) acct in normal mode, then could NOT see the 2 problem folders & files normally in Explorer. Any suggestions on the easiest way to get the 2 folders & files back to normal display? Hmmm... that sounds pretty odd - "HELP! My index.dat files are gone - help me get them back." Well, except that they're not really gone.
